DIGITAL TACHOMETER

A tachometer is essential for suitable outboard performance.
The engine speed can be monitored for most efficient operation.
In dual-engine applications, the tachometers can be used to set the throttle of each engine accu-
rately.
The digital tachometer includes the elapsed hour meter, the trim meter and the oil warning indicator.
Also, this meter can be used for both 2 and 4 stroke models by the switch settings.
